Application led December 3, 1913. Serial No. 804,347.

To all Iwhom t may concern:

Be it known that I, HARRY H. Hoon, a citizen of the United States, residing at Chicago, in the county of Cook and State of lllinois, have invented certain new and useful Improvements in Can-Heading Machines, of which the following is a specification.

This invention relates to machines for applying the heads or end pieces to the bodies or shells of tin cans, and has reference more particularly to that type of can-heading machines wherein the heads are joined to the bodies by crimping and clamping together interlocking flanges on the respective parts-` in such a manner as to make a liquid-tight joint without the use of solder. More specically, the machine of my present invention relates to that type of can-heading machines which employ one or more roller crimping dies that are mounted to rotate bodily around the flanged edge of the head and, simultaneously with their bodily rotary movement, are forced inwardly against the edge of the head to crimp and interlock the latter with the flange of the can-body.

The general object of the invention is to provide an improved and simplified canheading machine of this general type, more' struction and arrangement of rotary crimping head and its actuating mechanism characterized chiefly by the provision of a pair of successively acting roller crimping dies, one of which effects the initial crimping and interlocking of the flanges of the head and body and the other of which effects the final flattening and compacting of the flanges against the wall of the can body. Still another important object is to provide a canheading machine that shall be capable of easy adjustment to operate, upon cans of different heights. Other objects and advantages secured by the invention will be apparent from the following description, when taken `in connection with the accompanying drawings forming a part of this specification, in which- Figure 1 is a perspective elevation of the complete machine,as viewed from the deliv- Another importantY object is to provide a new and improved conery side thereof. Fig. 2 is a similar perspective elevation of the machine as viewed from the side opposite that shown in Fig. 1. Fig. 3 is a central vertical section, broken oft' slightly below the upper end in the vertical axial plane of the drive shaft. Fig. 4 is a horizontal section taken on the line 4 4 of Fig. 3 and looking downwardly. Fig. 5 is a horizontal section taken on the line 5-5 of Fig. 3, looking downwardly. Fig. 6 is an enlarged vertical axial section through one of the rotary crimping heads and its actuating mechanism. Fig. 7 is an enlarged central vertical section through the can-head feeding mechanism. Fig. 8 is a to plan view of a portion of the can-head feeding mechanism shown in Fig. 7. Fig. 9 is a vertical section taken on the line 9 9 of Fig. 8. Fig. 10 is a top plan view of a rotary cam which actua'tes the delivery fingers of the can-head feed mechanism. Fig. 11 is a top plan view of another portion of the can-head feed mechanism which moves the can head into position beneath the crimping head. Fig. 12 is a vertical section through a portion of the can-body feed mechanism. Figs. 13, 14 and 15 are details illustrating successive steps in the operation of crimping and locking the can head onto the can body, Fig. 13 showng the can head and body in starting position, Fig. 14 showing the two partially united by means of one of the crimping dies, and Fig. 15 showing the parts fully united through the agency of the other crimping dic. Fig. 16 is a sectional detail View on line 1(316 of Fig. 6.

Referring to the drawings, 1 designates as an entirety the base-plate of the 'machine adapted to be strongly secured to the floor by screws or bolts entered through holes 2 therein. Surmounting the base-plate 1 and conveniently cast integral therewith is .a casing designated as an entirety by3 that forms a housing for certain lower movable parts of the machine. Secured to one side of the housing 3 is an auxiliary housing 4 that also provides bearings 5 for the main driving shaft 6, this latter `carrying a loose pulley 7 and a friction clutch 8 sp ined on the shaft and actuated by a clutch-shifter 9. The casing 3 has a central vertical sleeve 10 (Fig. 3), on which is secured a cam block 11 containing` a peripheral cam groove 12. Rotatably mounted within the sleeve.10 is the tubular stem 13 of a rotary can-carrier 14, which is supported by anti-friction bearings 15 on the upper edge of the stationary sleeve and also registers at its outer edge with the upper edge of thecentral casing 3, pref-4 erably by a lap-joint 16. The can-carrier disk 14 is formed at equally spaced intervals therearound with vertical bearings 17 in which are mounted. `a plurality (herein shown as six) of the vertical slides 18, each of which is socketed through a portion of' its length to receive the stem 19 of a can-body chuck 20. Through the -stem 19 is formed an oblong slot 21, through which, and the slide 18,. passes a pin 22, and beneath the stem 19 is a cushion spring 23. The pin and slot connection, together with the' sprin 23,

ai'ords a sli ht cushioning eii'ect to the c uck 20, on whic that is keyed at 28 to a short vertical counter-shaft 29 journaled in bearings 30 and 3l and having formed on its upper .end a spur pinion 32 that meshes with and drives a large spur gear 33v that is keyed to the lower end of the tubular stem 13 of the cancarrier. By this mechanism a continuous rotary movement is imparted to the cancarrier and to the can-body chucking devices carried thereby. f

Extending through the tubular stem member 13 is a vertical tubular shaft 34 provided with an elongated key-way 35 containing'a key 36 by which it is keyed to the l tubular stem member 13 with capacity-for per end ofthe tubular member 13.

limited adjustment lengthwise of the latter.

The lower end of the tubularshaft .34 is threaded to receive a nut 37 that bears against the lower end of the member 13 and the lower side of the hub of the large gear \33. The shaft 34 is also threaded near its upper end to receive an adjusting nut 38, the 'lower end of which bears upon the lp- Y proper manipulation of the nuts 37 and 38, the tubular shaft 34 may be bodily raised or lowered to a limited extent to adapt the mavchine to the, handlingl of cans of different heights, as will hereinafter clearly appear. The tubular shaft 34 terminates at its upper end in an integral star-plate 39, shown in tolp plan .view in Fig. 5, to the points of w ich is secured, by meansV of bolts 40 and spacing sleeves 41, a rotary crimping-head carrier 42. This latter is cast with a plurality of' uniformly spaced vertically apertured bosses 43 grouped therearound and each forming a support for one of the crimping heads and its actuating mechanism hereinafter described. The rotary carrier 42 also has a central boss 44 (Fig. 3) in which is keyed a vertical shaft 45, the upper end of which shaft is journaled in a bearing 46 (Figs. 1 and 2) on the inner end of a horizontal arm or bar 47 that is mounted at its outer lend upon the upper end of a post 48, which latter is adjustably supported and secured at its lower end in a clamp bracket 49 on the main frame or housing 3. Surrounding the shaft and secured at its upper end to a plate 50 integral with the inner end of arm 47 is a circular cam block 51 formed with upper and lower circumferential cam-grooves 52 and 53, respectively.

Referring now to the crimping head and` its immediate actuating mechanism, which is best shown in the enlarged detail view, Fig. 6, 54 designates a tubular member that extends through a central vertical aperture 55 of the carrier boss 43 and is adjustably clamped'to the latter by upper and lower nuts 56 and57, respectively. The member 54 has, about midway of its length, a vertical slot 58, below the latter an annular shoulder member 59, and at its lower end has a threaded narrowed portion 60 carrying a nut 61. Rotatably mounted on the lower portion of the tubular member ,54 and confined between the shoulder 59 and the nut 61 is the hub 62 of a horizontal spur gear 63, which latter is formed with oppositely disposed radial slots 64. Resting upon and secured to the upper side of the gear 63 by screws 65 is a block 66 also formed with a pair of radial slots 67 registering with the slots 64 of the gear 63. Extending through the registering Slots 67 and 64 are a pair of levers 68 and 69, respectively, that are pivoted substantially midway of their length on pivot pins 70 extending transversely of the block 66. Said block is preferably provided with one or more auxiliary pivot holes 71 to enable the levers 68 and 69 to be adjusted radially of lthe center of the crimping head to accommodate cans of different diameters. The lower ends of the levers 68 and 69 are socketed as shown at 72 (Fig. 16) to receive headed studs or spindles 73, on

which latter are journaled the circular crimping dies 74 and 75. To secure the studs 73 in their sockets, the lower end portion of leach lever is split vertically, as shown at 76 and through the portions .of the lever lying on the opposite sides of the split 76 is assed a clamping screw 77. The die roller 4 is formed with a circumferential groove 74 (Fig. 14) which performs the first part of the metal crimping operation; and the die roller 7 5 has a corresponding groove 75 (Fig. 15) thatis wider and somewhat shallower than the groove 74 of the roller 74 and that performs the last part of the crimping operation, as best illustrated in the detail views Figs. 13, 14 and 15 to which fuller reference is made later.

Extending through and for some distance ab'ove the tubular member 54 is a tubular rod 78, the main function ofwhich is to serve as a knock-out device to dislodge finished cans from the lower end of the nut 61 that serves as a mandrel during the canheading operation. rThe rod 78 is threaded at its upper end and extends through a hole in an actuating arm 79, being confined on the latter by upper and lower nuts 80 and 81, respectively. The tube 78 also has a transverse slot 82 that registers radially with the slot 58. Within the tube 78, below the slot 82 is secured, by a pin 83, a plug 84 that forms an abutment for the upper end of a coil spring 85, the lower end of which abuts against the stem 86 of a chuck member 87 by which the can head is pressed upon the end of the can body just prior to and during the crimping operation. The stem 86 slides within the lower end of the tubular rod 78 and is confined therein by a pin 88 engaging a slot 89 in the steml 86. The actuating arm 79 has mounted on its inner side a roller 90 that travels in the cam groove 53, and said arm has an elongated hub 91 extending at-right angles thereto and slidably mounted upon a bearing stud or spindle 92 mounted in the boss 43. ln the idle position of the parts last described, the spring 85 forces the chuck-head 87 downwardly until the upper end of the slot 89 engages the pin 88; but when the can body, with the head or cap positioned thereon, is raised by the lower chuck 20 through the action ofthe cam 11, the upper surface of the head strikes and raises the upper chuck-head 87, thereby compressing the spring 85 and thus applying the force of the latter to the can head or cap.

Referring now to the mechanism for actuating the die rollers 74 and 75 radially of the crimping head, and referring first to Figs. 1, 2 and 3, on the upper end of each lever (S8 and 69 is mounted a transversely extending yoke 93, and the ends of the yokes on the two levers are connected by elastic connectors including tension springs 94. These springs obviously urge the upper ends of thelevers toward each other and their lower ends apart, thus holding the die rollers at their extreme outer positions. The rollers 74 and 75 are successively, and in the order named, gradually forced inwardly to effect the crimping operation by the mechanism now described. Slidably mounted within the tubular rod 78 is a central rod 95. lxtending through this rod near its lower end and also through the slots 82 and 58 is a cross-pin 90, on which is suspended a cam-holder or cage 97 that is slidably mounted upon the tubular member 54. Ro-

tatably mounted upon and within the cage 97 is a ring 98, in which are formed at diametrically opposite points vertical slots 99, and in said slots are set hardened steel vertical cams 100 and 101, respectively. Preferably, and as herein shown, behind the base of each cam is interposed a cushioning pad 102 of rubber, felt, or other suitable cushioning material which allows of a slight yield of the cams that enables the die rollers 74 and 75 to accommodate themselves to the slight irregularity produced b v the longitudinal seam of the can body. lt will be observed that the cam 100 is ot' shorter longitudinal extent than the cam 101. and is also slightly narrower than the latter. Mounted in the upper end of the lever ($8 is an adjustable cam contact finger 10i-l that coperates with the cam 100. and similarly mounted in the upper end of the companion lever 69 is an adjustable cam contact finger 104 that coperates with the cam 101. These fingers at their inner ends enter and slidably engage the slots 99 of the cam ring 98 and impart rotation to the latter. The central rod 95 is actuated from the cam groove 52 by almechanism similar to that which actuates the tubular rod 78, comprising an actuating arm 105 in which the upper end of the rod 95 is secured by upper and lower nuts 106 and 107, respectively, a roller 108 journaled on the arm 105 and traveling in the cam groove 52, and an elongated hub 109 on the arm 105 slidably engaging a stud or spindle 110 secured in the boss 43.

Referring to Fig. 3, the driving gears (33 of the several' crimping heads are rotated from a central master gear 111 with which they all mesh; said master gear 111 being keyed upon the upper end of a central vertical shaft 112 that extends through the tubular shaft 34 and below the latter and has keyed on its lower end a wide spur gear 113 with which meshes a spur gear 114 formed integrally with the bevel gear 27.

To the under side of the star-plate 39 is secured, by the bolts 40, a can-head carrier in the form of a circular plate 115 that lies a slight distance below the lower ends of the several crimping heads, and, beneath each of the latter, is formed with a hole 116 of suficient diameter to admit the passage therethrough of theupper end portion of a can body; said holes being preferably tapered or flared downwardly, as shown, so as to automatically guide or center the can bodies into axial alinement with theJ crimping heads. @n the plate 115 is secured a thin ring 115a having semicircular scallops 115 in its outer edge that register with the inner halves of the holes 116 and form guiding and centering devices for the can heads. y

The machine as thus far describe-d is 'complete for the purpose of uniting the heads tia or caps of cans to the bodies thereof, assuming that the bodies of the cans are successively positioned upon the chuck-plates of the rotary can-body carrier 14 as each chuck-plate 20 assumes substantially the p0- Sition of the right-hand chuck-plate 20 in Fig. 3, at which time the actuating roller '24 of said chuck-plate is at the low point of the stationary cam groove 12. As the can-body carrier 14 and the crimping-head carrier 42 rotate simultaneously and at equal speedsfrom right to left, as shown in Figs. 1 and 2, the chuck-plate 20, supporting a can body, is raised by the cam groove 12, carrying the upper end of the can body through the hole 116 of the can-head plate carrier 115. A can head of the general form illustrated at A in Fig. 13, having a circum ferential-fiange a with a more or less downthe parts assuming the relative positions shown at the bottom of Fig. 6. At this instant, the roller 108 enters a gradually in clined portion of the cam groove 52, and begins to raise the actuating cams 100 and 101 of the roller-dies 7 4 and 75. The cam 100 acts slightly in advance of the cam 101, thereby causing the roller-die 74 to effect the initial curling and crimping operation shown in Fig. 14; it being understood that the crimping head is rapidly revolvin on its own axis, whirling the roller-dies 4 and 75 rapidly around the upper margin of the stationary can body7 and head. As will be seen by reference to Fig. 14, the gradual inward movement of the roller-die 74, under the action of cam 100, curls the fiange a of the head and the fiange b of the body downwardly and inwardly, causing the inwardly curled marginal portion a to fold upwardly more or less between the cylindrical wall of the can body and the flange b. As the finger 103 drops ofl" the high point of the cam 100, the springs 94 retract the die 74 to 1dle positlon, and simultaneously the cam 101 forces the die 75 into operative engagement with the partially crimped and mterlocked fianges of the can body and head; and as the cani 101 Icompletes its upward movement, the die-roller 75 is gradually forced farther 1nwardly until the iianges of the can body and head are fiattened into closely crimped and interlocked relation substantially as shown in Fig. 15. During this operation it will be understood that the lower end of the nut 61 enters the shallow depression of the can head which lies inwardly of its marginal flange and acts as a mandrel in coperation with the roller dies to effect the thorough crimping and interlocking of the can body and head. In this connection it may be stated that the under side of the fiange a of the head is preferably coated with a rubber or similar composition indicated at C in vFig. 13 to form a gasket between the interlocked flanges a and This crimping operation continues upon each can during approximately one-half a revolution of the can-body and crimping-head carriers. As the roller 24 of each can-carrying member traverses the downwardly inclined portion 12 of the cam groove 12 shown by dotted lines in Fig. 3, the can body with the head crimped thereon in the manner described, of course, descends, and simultaneously the roller 90 enters the dip 53 of the cam groove 53 also shown in dotted lines in Fig. 3, thereby depressing the kick-out rod 78 and forcing the lipper end of the can off the lower end of the mandrel 61, whereupon the finished can is removed from its lower chuck 20.

Of course, the feeding of the can bodies and heads to the machine, and removal of the finished cans may be effected either by hand, or by any suitable feed and delivery mechanisms. To render the machine entirely automatic in character, it is, of course, highly desirable to provide such auxiliary mechanisms for performing any or all of the functions of feeding the can lbodies and the can heads to the machine and withdrawing the finished cans therefrom. I have, therefore, herein shown mechanisms for this purpose which will next be described; but it is to be understood that the specific forms and constructions of these several mechanisms are not essential to the present invention.

Referring first to the can-body feed mechanism, 117 (Fig. 1) designates an inclined chute through which the can-bodies B pass by gravity in horizontal position into the upper square end of a can-righting device, which latter comprises an obliquely disposed casing 118 of the general form indicated in Figs. 1 and 2, and a rotary carrier mounted within said casing consisting essentially of an obliquely disposed carrierdisk 119 formed with an angular-ly bent marginal fiange 119 in which are peripheral notches or seats 120 into which the can bodies B successively drop through the square upper open end of the casing and are carried through a half circle being guided at one end by the curved and warped outer or rear wall of the casing 118 and at the other end by a cone-shaped guard 121 (Fig. 12) which may conveniently be cast integral with the rotary carrier 119. During this travel each can is shifted from the horizon- Laaasee tal position shown at the upper end of Fig. 12 to the vertical position shown at the lower portion of Fig. 12, the can being deposited upright upon a plate 122. The lcarrier-disk 119 is journaled upon an oblique bearing stud 123 supported by'a bracket 124, and is rotated from the large gear 33 (Fig. 5) through an intermediate spur gear 125, a spur gear 126 fast o n the lower end of a vertical shaft 127, a bevel gear 128 on the upper end ,of shaft 127, and a bevel gear 129 on the under side of the carrier-disk 119. rllhe upper end of shaft 127 is supported in a vertical bearing boss 130 integral with the bracket 124.

Referring to Figs. 4 and 12, secured to the plate 122 is a curved guide 131, one end 1131a of which extends beneath the lowest point of the carrier-disk 119, as shown in Fig. 12, while its opposite end 131b overhangs the rotary plate 14 that carries the chuck members 20. Mounted concentrically with the guide 131 .upon an upright shaft 132 (whichv carries the intermediate gear 125) is a sweep consisting of a disk 133 having a plurality of approximately semi-circular notches 133 in its periphery. The rotation of the sweep 133 is so timed relatively to the rotation of the cam-righting disk 119-.and of the rotary chuck-carrier 14 that it engages a can body simultaneously with the deposity of the latter upright on the supporting plate 122, carries it around in sliding contactwith the guide 131, and deposits it upon one of the can-body chuck-plates 20 just as the lat,

ter comes opposite and beneath the inner end 131b of the guide 131. The can body at this point passes from the control of the sweep 133 and guide 131b onto the chuck-plate 20 being accurately positioned and centered on the latter by the centering device 25. At this point the delivery of the can body onto the chuck-plate 20 is complete, and the can bod is then subjected to the operations allrea y described. 1

'llhe above described can-.body teed mechanism is, of course, practicable and usable in its entirety only with empty can-bodies or shells for the application of one of the endpieces or heads thereto. .For the purpose of applying the other end-piece or head to filled cans other or a modified feed mechanism not involvin the can-righting device would obviously e required.

Referring-next to the mechanism lor feed l ing the can heads into the machine, and referring mainly to Flgs. 7 to 11 inclusive, 134 designates a group of vertical rods secured at their lower ends in an annular base member 135 and forming with the latter a hopper yto receive a `stack of can heads A,

as lllustrated in Figs. 1 and 2. @n thelower end of the annular base'member 135 is a radial Harige 136 (Figs. 8 and 9) and through the lower edge ot said base member and its flange are milled a series of radial grooves 137. The lower flanged edge of the annular base -member 135 is slightly countersunk to an extent equal to about one-halt the' 140, which latter in turn rests upon the main v l supporting -plate 141 (Figs. 1, 7 and 11). This latter plate is disposed inthe horizontal plane of the circular can-head carrier plate 115, and, as best shown in Fig. 11, has a concave edge 141- `that substantially registers with the circular edge of the plate 115. In this main supporting plate 141 is a shallow channel 142, the inner end of which extends to the concave edge 141 of' the plate, while its outer edge merges into a circular hole 143 that is concentrically beneath the vertical can-head hopper. In the radial slots' 137 of the hopper base 135 are mounted a series of slides 144, in the inner ends of which are secured thin flat fingers 145 and v146 that, when the slides'are in their innermost positions project slightly inwardly of the circular wall of the ring base 135 of the hopper. In the construction herein shown there are six slides and fingers at equally spaced intervals around the lower edge ol' the hopper base, and it.will be observed that the fingers 145, which alternate with the fingers 146, are in a lower plane than the latter by substantially the .thickness of a can head. J ournaled upon the hopper base 135 is a spur gear 147 shown in bottom plan in Fig. 10, on the under side of which is formed a ca m groove 148 .that receives rollers 149 mounted on the upper sides of the slides 144, and, as the gear 147 is rotated, eHects alternate in-and-out movements of the slides carrying the lingers 145 and 146,

and, .upon the retraction of the latter hngers, is dropped lontothe plate 141 above the hole 143; said ,hole and the shallow groove 142 accommodating the central depressed or counterlsunk portion of the can ead. At the instant that the bottom head drops od' the fingers 145, thelingers 146 enonto lthe plate 141V ator to readily raise and remove from beneath a surplus stock of heads, or to adjust the latter should there be any irregularity in the feeding owing to malformation of the heads, orotherwise.

Each head, when droppedin the manner described onto the plate 141 is transferred from the latter onto the rotary can-head carrier 115 directly over one of the holes 116 of the latter by means of a sweep consisting, as best shown in Fi 11, of a three-arm star wheel 150 that lies between the plates 138 and141 and occupying a space formed by omitting a portion. of the spacer-plate 140. The arms of the sweep 150 engage the deposited can heads edgewise and sweep them bodily along the guide-groove 142 onto the carrier 115 directly above the holes 116 of the latter; the curved edges 115 of the ring 115a acting in coperation with the sweep 150 to accurately center the heads over the holes 116. The spur gear 147 that actuates the cam 148 controlling the Slides 144 is, as best shown by Fig. 1, continuously rotated by a wide pinion 151 fast on the upper end of a vertical shaft 152, on the lower end of which latter is a sprocket wheel 153 (Fig. 4) that is connected by a sprocket chain 154 with a sprocket 155 (Fig. 2) fast on the vertical drive shaft 127 of the canbody feed mechanism. The main supporting plate 141 of the can-head feed mechanism vis adjustably secured by a bracket 156 (Fig. 1) to the post 48, so as to be capable of vertical adjustment corresponding with the vertical adjustment of the rotary carrier of the crimping heads; and to preserve the continuity of the driving mechanism of thespur gear 147, the pinion 151 is made of sufficient height, as shown, to be operative within the contemplated limits ofvadjustment. The star wheel 150 that shifts the deposited can heads successively into nal position on the guide-plate 115 is mounted upon the upper end of, and actuated by, the same vertical shaft 132 which carries and` ac tuates the can-body sweep 133,-and the relation of the two sweeps on said shaft is such that a can body and a can head are simultaneously shifted inwardly into vertically registering positions onto the can-body chucks 2O and can-head carrier 115, respectively.

In Figs. 1, 4 and 5 I have illustrated a simple device for automatically 'effecting the successive discharge of the headed cans from the machine. This device comprises essentially a curved guide member 157 (Fig.

4) whichvmay conveniently be cast integral with the guide member 131 of the feedingin mechanism, a rotary sweep 158 located opposite the guide member 157, and a disc arge chute or channel 159 disposed in a tangential relation to the sweep 158 and guide 157.. The sweep 158 is mounted upon a short vertical shaft 160, on the lower end of which is a spur gear 161 of the same size as the spur gear 125 on shaft 132 and meshing with and driven by the master spur gear 33. As each chuck-plate 20 reaches approximately its lowest position carrying a headed can thereon, it meets and registers with one of the concaves of the sweep 158, as shown by Fig. 4, at which point the sweep 158 and the guide 157 coperate in displacing the can from the chuck-plate 20 and conveying and directing it off through the discharge chute 159.

From the foregoing it will be apparent that the machine, when equipped with the can-body and can-head feed mechanisms shown and described, and with th(` delivery mechanism last described, is entirely automatic in its character, requiring only the services of an attendant to supply can bodies and can heads tothe supply chute and hopper, respectively, and to dispose of the iinished Cans as they are delivered through the discharge chute 159. If occasion arises to adapt the machine tothe handling of longer or shorter can bodies, the necessary adjustment is easily and quickly effected by a simple manipulation of the nuts 37 and 38 (Fig. 3) by means of a suitable Spanner wrench or like tool, the raising or lowering of the arm 47 on post 48 or the adjustment of the latter in its supporting bracket 49, and the raising or lowering of the can-head feed mechanism to correspond by adjusting the supporting bracket 156 upon the post 48. Ample provisions are,l of course, made for effecting the oiling of all parts requiring lubrication, and to a considerable eX- tent oil-cups for this purpose are indicated on the drawings; but such oiling devices, being of a common and known character, are not herein particularly described.

It will be readily understood by those skilled in this art that the apparatus herein shown and described is capable of variation and modification as to its details of structure and organization to a considerable extent without departing from the principles of operation involved or lessening the eiciency of the apparatus for its described and intended purposes. Hence it is to be understood that the invention is not limited to the exact constructions and relative arrangements of the coperating parts otherwise than as clearly pointed out in the appended claims.
